Oh... the porn. So. Much. Porn.
As with many IT jobs, porn is everywhere, and it doesn't matter who you're talking to (Grandma's, Grandpa's, Soccer moms, etc) someone always has a nice surprise for you.
"My first experience with a customer was a guy who came in specifically for issues with Safari crashing on his iPhone. I asked him if I could see the issue, and he handed me his phone. So being that his issue was with Safari, I opened Safari, and what did I find - 30+ tabs of pornographic videos all playing at the same time.
He practically jumped when he realized what he had left open, and I tried to stifle a laugh as I quickly tried to close the tabs and turn down the volume. Part way through, the app crashed, so I had to load it up again and continue with closing the tabs.
"When I finally finished, I explained the importance of closing tabs, especially if they were running high-usage content like videos. I looked in his crash logs and saw safari was the only app struggling but noticed that it was now working great after closing all the tabs. I explained that I thought it was just that simple, and he thanked me quickly and left.
